/**
 * 使用elasticsearch的步骤：
 * 1、导入依赖
 *       <dependency>
 *             <groupId>org.elasticsearch.client</groupId>
 *             <artifactId>elasticsearch-rest-high-level-client</artifactId>
 *             <version>7.6.2</version>
 *       </dependency>
 * 2、编写配置,给容器中注入一个RestHighLevelClient
 * 3、参照官方文档
 *
